To all whom it 11i/ty concern.:

Beit known that I, FRED VITTE, a citizen of the United States, residingat Okawville, in the county of Washington and State of Illinois, haveinvented certain new and useful Improvements in Grain-Separators; and Ido hereby declare the following to bea full, clear, and exactdescription of the invention, such as will enableothers skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in grain-separators, and is moreparticularly designed as an improvement upon that form of separatorknown to the trade as The Belleville Separator.

In the use of the Belleville separator as now constructed it has beenfound that the shoe thereof has failed to prevent the passage of trash,sticks, dro., therethrough, and the wheat when issuing from thedelivery-spout is burdened to a considerable extent with such trash,sticks, tbc.

It is therefore the object of the present invention to provide animproved form of shoe the construction of which is such that a thoroughseparation of trash and the like from the wheat will be effected and thelatter when delivered will be in a perfectly clean state.

With this general object in view and others which will appear as thenature of the irnprovements is better understood the invention consists,substantially, in the novel construction, combination, and arrangementof parts, as will be hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the appended claims In thedrawings, Figure 1 is a longitudinal sectional View of a grain-separatorprovided with a shoe constructed in accordance with the presentinvention. Fig. 2 is a similar view,on an enlarged scale,of the shoeremoved.

Referring to the drawings, the numeral 1 designates athreshing-cylinder; 2 and 3, a

pair of separating-pans; 4, a shoe; 5, a rotary fan forcreating a blast,and 6 a tailingselevator receiving the discharge from the shoe forconveying the tailings back to the cylinder.' The parts enumerated areof the ordinary construction as employed in the Belleville separator,excepting the shoe 4t, and in view of this it is not deemed essential toenter into a detail description of the same.

The invention lies solely in the construction of the shoe Il, andreferring to Fig. 2 it will be observed that such shoe comprises aframework 7, which is of the ordinary construction. Arranged in theupper portion of the frame 7 is an upper riddle 8, )rovided with punchedopenings 9, below which project the lips 10, formed by the punchingoperation, and this riddle is likewise of the ordinary construction. Theframe 7, however, at its end most remote from the fan 5 is provided witha transverselyextending tailboard spout 11, and over said spout theupper riddle S is designed to project, as clearly shown. It will also benoted that the degree of inclination of the riddle S is very slight, sothat said riddle lies in what is almost a horizontal plane, and arrangedbeneath the riddle 8, at the bottom of the frame 7, and inclined towardthe fan 5 is a screen 12, the upper end of which abuts against thetailboard spout 11.

Interposed between the upper riddle S and the screen 12 is an inclinedlower riddle 13, having circular openings 14E, the rear edge of saidriddle 13 resting upon the upper edge of the nearest side of the spout11; but the length of the riddle 13 is about one-half only of the riddle8, and the forward edge of said .riddle 13 thereby lies at about themiddle of the riddle 8 and is in close Contact therewith. The riddle 13inclines in the same direction with the riddle 8; but said riddle 13lies at an angle of from sixteen to twenty degrees to the riddle S,whereby the tailings passing through the riddle 8 and upon the riddle 13will be precipitated by the latter to the spout 11 without anydifficulty whatever.

The shoe et at the lower end of the screen 12 is provided with atransversely-extending delivery-spout 15, through which the wheat passesfrom the shoe toa suitable'receptacle.

The operation of the herein-described separator is as follows: The wheatbeing fed to the cylinder 1 passes through the machine in the usualmanner, and when the grain arrives at the riddle 8, together with` thoseheads which have not been sufficiently broken by the cylinder 1, thesame passes through the openings of the riddle 3 and gravitates to thelower riddle 13. ous that the majority of the uncrushed heads It is ofcourse obvi-l IOO will pass over the rear edge of the riddle 8 and intothe tail-spout 11; but it has been found that unless the lower riddle 13is employed that portion of the heads passing through the riddle 8 willdescend to the screen 12. Herein lies the advantage of the lower riddle13, which while permitting the free passage of the grain will preventthe uncrushed heads being fed to the screen 12 and will in lieu thereoffeed the heads to the tailboard spout 11, whence the same pass to theelevator 6 and are carried thereby to the cylinder 1, so that the lattermay again act upon said heads. Moreover, the trash, sticks, &c., whichare the usual accompaniment of the grain from the riddle Sto the screen12, are diverted from the screen 12 and fed to the tailboard spout 11,so that the grain which passes down the screen 12 and into thedeliveryspout 15 is perfectly free and clean.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. In a shoe for grain-separators, the combination with the framethereof provided at its rear end with a tail-board spout, of an upperriddle spaced above said spout and having its rear end projecting overthe spout, a screen arranged at the bottom of the frame and having itsrear end in contact with the forward edge of said spout, said screeninclining forwardly and downwardly from the spout, and a lower riddleinterposed between the upper riddle and the screen, said lower riddlebeing inclined reversely to the screen and having its rear end restingupon the forward edge of the tail-board spout and its forward end inclose contact with the upper riddle, whereby the tailings dischargedfrom the upper riddle are received by the lower riddle and deiiectedthereby from the screen into the tail-board spout.

2. In a shoe for grain-separators, the combination with the framethereof provided at its rear end with a tail-board spout, of an upperriddle spaced above said spout and having its rear end projecting overthe spout, a screen arranged at the bottom of the frame and having itsrear end in contact with the forward edge of said spout, said screenincliriing forwardly and downwardly from the spout', and a lower riddleinterposed between the upper riddle and the screen, said lower riddlebeing inclined reversely to the screen and having its rear end restingupon the forward edge of the tail-board spout and its forward end inclose contact with the upper riddle at a point intermediate the ends ofthe latter, whereby the tailings discharged from the upper riddle arereceived by the lower riddle and deiiected thereby from the screen intothe tail-board spout.

In testimony whereof I affix my signature in presence of two witnesses.

FRED WITTE.
